Many of these 101 science experiments are great, but there's also plenty of standard fare, such bottle gardens, construction of a circuit, and the perennial erupting volcano. What makes this book special is the clean, simple format with equally simple instructions. The experiments are grouped into 11 categories, including water and liquids, electricity, motion and machines, and the senses. Most of the experiments are laid out in seven steps or less. Crisp, color photographs and concise captions make each step easy to follow. Children of various ages are shown performing many of the procedures. A warning about being a safe scientist is fairly inconspicuous on the verso of the title page; a symbol for adult supervision is described there and appears throughout the text where cutting, heating, and potentially harmful substances are required. Young scientists should find plenty of ideas for experiments and activities that can be done with ordinary household items and found materials.
